BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Delosperma plant, botanically known as Delosperma cooperi, commonly called Trailing Ice Plant and hereinafter referred to by the name ‘Dodelrochryye’.

The new Delosperma plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new early-flowering Delosperma plants with numerous attractive flowers.

The new Delosperma plant originated from a self-pollination in July, 2016 of a proprietary selection of Delosperma cooperi identified as code number DL-0003, not patented. The new Delosperma plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated self-pollination in a controlled environment in Rheinberg, Germany in May, 2019.

Asexual reproduction of the new Delosperma plant by vegetative terminal cuttings in Rheinberg, Germany, since June, 2019 has shown that the unique features of this new Delosperma plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Delosperma have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dodelrochryye’. These characteristics in combination distinguish ‘Dodelrochryye’ as a new and distinct Delosperma plant:

-   -   1. Upright and outwardly spreading plant habit; typically used         as a groundcover.     -   2. Moderately vigorous growth habit and rapid growth rate.     -   3. Freely basal branching habit; dense and bushy habit.     -   4. Early and freely flowering habit.     -   5. Large bright yellow-colored flowers with white-colored         centers.     -   6. Good garden performance.

Plants of the new Delosperma differ primarily from plants of the parent selection in flower color as plants of the new Delosperma have bright yellow-colored flowers with white-colored centers whereas plants of the parent selection have red-colored flowers with pink-colored centers.

Plants of the new Delosperma can be compared to plants of Delosperma cooperi ‘Dodelrochrynere’, disclosed in U.S. Plant patent application Ser. No. 16/873,418 filed concurrently. Plants of the new Delosperma differ primarily from plants of ‘Dodelrochrynere’ in flower color as plants of the new Delosperma have bright yellow-colored flowers with white-colored centers whereas plants of ‘Dodelrochrynere’ have intense red purple-colored flowers with light red purple-colored centers.

Plants of the new Delosperma can also be compared to plants of Delosperma cooperi ‘Jewels of Desert Topaz’, disclosed in U.S. Plant Pat. No. 23,492. In side-by-side comparisons, plants of the new Delosperma differ from plants of ‘Jewels of Desert Topaz’ in the following characteristics:

-   -   1. Plants of the new Delosperma are more compact than plants of         ‘Jewels of Desert Topaz’.     -   2. Plants of the new Delosperma have bright yellow-colored         flowers with white-colored centers whereas plants of ‘Jewels of         Desert Topaz’ have yellow orange-colored flowers with         red-colored petal apices.     -   3. Plants of the new Delosperma have shorter peduncles than         plants of ‘Jewels of Desert Topaz’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Delosperma plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Delosperma plant.

The photograph on the first sheet (FIG. 1 of 2) is a side perspective view of a typical flowering plant of ‘Dodelrochryye’ grown in a container.

The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical flowering plant of ‘Dodelrochryye’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 22-cm containers during the spring in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Delosperma production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched once three weeks after planting and were three months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
